+ * What: /sys/fs/orangefs/perf_counter_reset
+ * Date: June 2015
+ * Contact: Mike Marshall <hubcap@omnibond.com>
+ * Description:
+ * echo a 0 or a 1 into perf_counter_reset to
+ * reset all the counters in
+ * /sys/fs/orangefs/perf_counters
+ * except ones with PINT_PERF_PRESERVE set.
+ *
+ *
+ * What: /sys/fs/orangefs/perf_counters/...
+ * Date: Jun 2015
+ * Contact: Mike Marshall <hubcap@omnibond.com>
+ * Description:
+ * Counters and settings for various caches.
+ * Read only.

+ * Length of perf counter intervals in
+ * seconds.
+ *
+ *
+ * What: /sys/fs/orangefs/perf_history_size
+ * Date: Jun 2015
+ * Contact: Mike Marshall <hubcap@omnibond.com>
+ * Description:
+ * The perf_counters cache statistics have N, or
+ * perf_history_size, samples. The default is
+ * one.
+ *
+ * Every perf_time_interval_secs the (first)
+ * samples are reset.
+ *
+ * If N is greater than one, the "current" set
+ * of samples is reset, and the samples from the
+ * other N-1 intervals remain available.
+ *
+ *
+ * What: /sys/fs/orangefs/op_timeout_secs

+ * What: /sys/fs/orangefs/slot_timeout_secs
+ * Date: Jun 2015
+ * Contact: Mike Marshall <hubcap@omnibond.com>
+ * Description:
+ * "Slot" timeout in seconds. A "slot"
+ * is an indexed buffer in the shared
+ * memory segment used for communication
+ * between the kernel module and userspace.
+ * Slots are requested and waited for,
+ * the wait times out after slot_timeout_secs.
